Now we are ready to use Phone API from QML side. Following is how QML code will look like. In code we are creating Phone object. On any call related event callUpdated signal will be called. So we are handling that signal in onCallUpdated event. Please note that we can not access Call's properties with QML, as its not derived from QObject, so if you need to access properties of Call then you need to forward call to C++ and handle it there.
